[Apocalyptic Evolution] [Roulette Draws] [Growing Equipment] [Decisive and Ruthless]
A dark void tore open the sky, and mutant beasts poured into the cities.
Humans dug crystal cores out of the beasts' skulls, then used key fragments to activate mysterious roulettes and draw enhancement serums, weapons, and armor, trading their lives for a chance to evolve.
Eight months after the cataclysm, nineteen-year-old Lu Chen was cornered in front of a beast's nest.
His attackers wanted his crystal cores, and they wanted him to serve as bait to lure the beasts away.
Lu Chen took one man's knife, shoved his corpse into the nest, and carried his last three white cores to the roulette.
What he produced was a nearly colorless, broken key fragment among his younger brother's belongings. There was only one line written on the cloth wrapped around it:
"Take this and find the roulette."
Ordinary key fragments activated the roulette, and whatever you drew was left to luck.
But his fragment let him choose what to draw.
He still had to pay the crystal cores, but he could pick the serum and weapons he wanted.
From the white roulette to even higher-level, unknown roulettes, Lu Chen gripped his short blade and began to vie for powers that had once seemed beyond his reach.
But as he activated the roulette again and again, the secret his younger brother had left behind gradually came to light...
Humans were choosing the rewards inside the roulette.
And the things behind the roulette were choosing humans, too.
